AIRCIRCULATING MECHANISM.

Specification of Letters Patent.

Patented May 9, 1916.

Application led October 5, 1914. Serial No. 865,216.

T 0 all whom it may concern:

Be it known that I, WILLIAM A. FREE- MAN, a citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented a new and useful Air-Circulating Mechanism, of which the following is a specification.

The present invention relates to improvements in air circulatin mechanisms, one object of the invention eing the provision of a mechanism which is adapted to be convertible for heating or cooling air during its circulation so that such air may be supplied for increasing or decreasing the temperature in homes, office buildings and the like, the same including means whereby a refrigerating fluid such as ammonia gas may be introduced to effect the water which in turn properly reduces the temperature of air in close proximity thereto and when in transit, the coils for containing the ammonia being convertible to receive hot water, steam or other heating means to thus heat the water for in turn heating the air in transit.

A further object of the present invention, is the provision of a device of this character in which the casing is divided into a plurality of compartments, the alternate ones of which are adapted to contain water, brine, or other liquid which is either heated or cooled by the passage of the proper medium through coils located therein, while the other alternating compartments constitute air receiving and transmitting means so that the air contained therein may be efi fected by the heated or cooled liquid and delivered to any point.

With the foregoing and other objects in view, which will appear asthe description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

'In the drawings: Figure 1 is a vertical central sectional view through the complete apparatus, the circulating means for the air and the ammonia for cooling or for the heating fluid to the coils not being shown. Fig. 2 is a section taken on line 2 2 of Fig. 1.

Referring to the drawings, the numeral 1 designates the casing, which is preferably made rectangular in shape and is divided by the plurality of sets of parallel partitions 2 into a plurality' of alternating liquid compartments 3 and air compartments 4, such compartments extending the full width and height of the casing 1 and being isolated from one another.

Adapted to be mounted within the water compartments 3 are the coils 5, which are 1n communication with each other through the alternately disposed connections 5 for the proper circulation of the cooling or heating fluid which is introduced at the pipe G through the valve 7 into the inlet plpe 8 and passes through the coils 5 to the outlet pipe 9. Where the coils 5 are adapted to receive ammonia gas for cooling the liquid in the compartments 3, the usual pump and condensing mechanism for the ammonia is used, and where the coils are adapted to contain steam or hot water, the pipes 6 and 9 are connected to create the desired circulation. Connected to-the pipe 8 and in communication with the coils 5 is the valve 8', which is connected to control the admission of the respective cooling or heating fluids to the coils. To drain the water from the compartments 3, and to regulate the height thereof, the upstanding overflow pipes 10 are disposed therein.

Air is directed by any desired means, either by pressure or by suction into the pipe 17 which is in communication with the upper end of the air compartment -1 at the extreme right of the apparatus, the lower end of the compartment 4 being in communication with the lower end of the next compartment 4 through the lower conduit 12 and the upper end of the compartment 4 is in communication with the last compartment 4 at its upper end by the conduit 13. Leading from the lower end of the extreme compartment 4 at the eXtreme left, is the air directing pipe 14, which supplies the heated or cooled air to the desired portion of the building. Any number of compartments 3 and 4 may be employed according to the size of the apparatus and the amount of space in the building to be heated or cooled.

From the foregoing description, it is apparent that the present apparatus is particularly adapted for heating or cooling air and supplying the same to houses, trains, office buildings and the like, it merely being necessary to mount the present apparatus so thatl the ammonia may be used for cooling purposes or steam or hot water for heating purposes. The current of air as before stated is supplied in the pipe 7 and through the vertical compartments by pressure or suction as may be found most expedient.

What is claimed is An air circulating apparatus, including a casing having a plurality of vertical partitions therein dividing the casing into alternately disposed liquid and air compartiments isolated from one another, the air compartments being connected in series and having an inlet and outlet at opposite ends of the casing, whereby the air passes in a zig-zag route through the air compartments, a plurality of coils connected in series and disposed in the liquid compartments for receiving a fluid for effecting the temperature of the liquid,` and upstanding overflow pipes in the liquid compartments.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
